MCA - 1360 30,36,46, or 60 grit Stoneblast® was developed specifically for the lettering of granite monuments. Packaged in 50-pound cartons/boxes (40 per full pallet). Stoneblast® is made of zirconium oxide and aluminum oxide fused under carefully controlled conditions to produce a chemically inert abrasive alloy, zirconia alumina. The abrasive reduces wear on interior nozzle surfaces because it only fractures on direct impact. Stoneblast® is a register product of Saint-Gobain (formally Norton Abrasive).

Full pallet purchases are the most economical.

This straight grit type of Stoneblast® is dependant on grit demands of other industrial markets and at times is not readily available.
